IBM Lotus® Notes® and Lotus iNotes® 8.5.1 on Citrix XenApp™ 4.5/5.0: A scalability analysis

By Brian Gallagher, Gary Denner, Jeremy Flynn, Swikar Sugandhi and Lee Mosqueda

This white paper provides an overview and recommendations for how to get the most from your IBM Lotus® Notes® 8.5.1 client on the new Citrix XenApp™ 5.0 server. In particular, we show that, by tuning your environment so that you get the most from your applications, you can realize significant improvements in running the Notes client on XenApp. This is true for both the standard and the basic configurations of Lotus Notes.

Moreover, the new support for Microsoft® Windows® 2008 SP2 by Notes 8.5.1 together with memory improvements means we can scale to even higher numbers than before at a much reduced cost. Also presented are the testing environment, tuning parameters, and the workflows that were executed to gather the scalability data on Notes 8.5.1.
